Selected Experience
Healthcare Analyst II
Medica
Minneapolis, MN
Present - 2021
- Collaborated with business owners to evaluate and improve programs assisting members. Used statistical models and simulations to understand variance of cost savings estimates. Collaboratively developed a strategy to generate additional $1,000,000 annualized savings.
- Translated actuarial completion factors from spreadsheets to SAS code for automation purposes. Reduced delivery time of monthly completion factors from a few days to a few hours. Implemented a more granular way to estimate these factors, resulting in 35% prediction error reduction.
